Formula One will have a new chief doctor in 2013 after the FIA decided not to renew the contract of Gary Hartstein.

Hartstein has worked in Formula One since 1997 and replaced the late Sid Watkins as chief doctor in 2005, working at every grands prix since. However, Hartstein revealed on Twitter that he had been informed he would not be kept on in the role past the end of the current season.

"Have just been informed that president of the FIA and president of FIA medical commission have decided not to renew my Formula 1 contract," Hartstein wrote. "Not sure about the "why's" of the decision, but not down to me to know.

"Brazil will therefore be my 247th and last Formula 1 Grand Prix. It's been a life changing experience and something I'll never forget. If I've brought even a small bit to this sport of what it's brought me in personal fulfilment then it was all worth it."
